Both BRAF V600E Mutation and Older Age (≥65 Years) are Associated with Recurrent Papillary Thyroid Cancer

Purpose This study was designed to examine the aggressive features of BRAF -positive papillary thyroid cancer (PTC) and association with age. Methods We compared the clinicopathologic parameters and BRAF V600E mutation status of 121 elderly (age ≥65 years) PTC patients who underwent thyroidectomy fr...

Results Younger and elderly PTC patients had similar incidences of BRAF -positive tumors (41% vs. 38%; p  = 0.67). The elderly cohort was more likely to have smaller tumors (mean 1.6 vs. 2.1 cm; p  = 0.001), present with advanced TNM stage (36% vs. 19%; p  = 0.008), and have persistent/recurrent disease (10% vs. 1%; p  = 0.006). BRAF -positive status was associated with PTC that were tall cell variant ( p  &lt; 0.001), had extrathyroidal extension ( p  &lt; 0.001), lymph node involvement ( p  = 0.008), advanced (III/IV) TNM stage ( p  &lt; 0.001), and disease recurrence ( p  &lt; 0.001). Except for lymph node involvement, the association between aggressive histology characteristics at presentation and BRAF -positive PTC also was observed within the age-defined cohorts. In short-term follow-up (mean, 18 months), persistent/recurrent PTC was much more likely to occur in patients who were both BRAF -positive and elderly (22%). Conclusions BRAF mutations are equally present in younger and older patients. Aggressive histology characteristics at presentation are associated with BRAF -positive PTC, irrespective of age. However, the well-established association of BRAF with recurrence is limited to older (age ≥65 years) patients.</description><identifier>ISSN: 1068-9265</identifier><identifier>EISSN: 1534-4681</identifier><identifier>DOI: 10.1245/s10434-011-1781-5</identifier><identifier>PMID: 21594703</identifier><language>eng</language><publisher>New York: Springer-Verlag</publisher><subject>Adult ; Age Factors ; Aged ; Aged, 80 and over ; Carcinoma, Papillary - genetics ; DNA, Neoplasm - genetics ; Endocrine Tumors ; Female ; Follow-Up Studies ; Humans ; Male ; Medicine ; Medicine &amp; Public Health ; Middle Aged ; Neoplasm Recurrence, Local - genetics ; Neoplasm Recurrence, Local - pathology ; Neoplasm Recurrence, Local - surgery ; Oncology ; Point Mutation - genetics ; Polymerase Chain Reaction ; Prognosis ; Proto-Oncogene Proteins B-raf - genetics ; Retrospective Studies ; Risk Factors ; Surgery ; Surgical Oncology ; Survival Rate ; Thyroid Neoplasms - genetics ; Young Adult</subject><ispartof>Annals of surgical oncology, 2011-12, Vol.18 (13), p.3566-3571</ispartof><rights>Society of Surgical Oncology 2011</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c403t-cf79c43ae3c2bc9b1d0dca2065859429b21adbd459f442febb13f72ed17a0ab93</citedby><cites>FETCH-LOGICAL-c403t-cf79c43ae3c2bc9b1d0dca2065859429b21adbd459f442febb13f72ed17a0ab93</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://link.springer.com/content/pdf/10.1245/s10434-011-1781-5$$EPDF$$P50$$Gspringer$$H</linktopdf><linktohtml>$$Uhttps://link.springer.com/10.1245/s10434-011-1781-5$$EHTML$$P50$$Gspringer$$H</linktohtml><link.rule.ids>314,777,781,27905,27906,41469,42538,51300</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/21594703$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Howell, Gina M.</creatorcontrib><creatorcontrib>Carty, Sally E.</creatorcontrib><creatorcontrib>Armstrong, Michaele J.</creatorcontrib><creatorcontrib>LeBeau, Shane O.</creatorcontrib><creatorcontrib>Hodak, Steven P.</creatorcontrib><creatorcontrib>Coyne, Christopher</creatorcontrib><creatorcontrib>Stang, Michael T.</creatorcontrib><creatorcontrib>McCoy, Kelly L.</creatorcontrib><creatorcontrib>Nikiforova, Marina N.</creatorcontrib><creatorcontrib>Nikiforov, Yuri E.</creatorcontrib><creatorcontrib>Yip, Linwah</creatorcontrib><title>Both BRAF V600E Mutation and Older Age (≥65 Years) are Associated with Recurrent Papillary Thyroid Cancer</title><title>Annals of surgical oncology</title><addtitle>Ann Surg Oncol</addtitle><addtitle>Ann Surg Oncol</addtitle><description>Purpose This study was designed to examine the aggressive features of BRAF -positive papillary thyroid cancer (PTC) and association with age.
